Function for corrupted kernel package

Question

I am currently testing a kernel tracking mechanism (e.g. dump_stack and frame_unwind). I want to know if the kernel tracking engine can get backtracking again if the kernel stack is damaged. If not, what will be the result in this case. Please suggest me a way so that I can damage the kernel stack by writing a function (which I will insert in some kernel execution path) or a module.

Answer 1

Other:

#define VALUE 1
#define HUGESIZE 50
void overflow()
{
    char buffer[0];
    printk("Overflowing stack.. \n");
    memset(buffer, VALUE, HUGESIZE);
}

Answer 2

How about this:

void overflow_stack() {
    int p[1];
    int i;

    for(i = 0; i < 1024; i++) {
        p[i] = i;
    }
}
